INSULATION COATING COMPOSITION FOR NON-AROMATIC ELECTRICAL SHEET, METHOD FOR MANUFACTURING SAME, AND NON-AROMATIC ELECTRICAL SHEET TO WHICH INSULATION COATING COMPOSITION IS APPLIED

摘要

Disclosed is an insulating film composition of a non-oriented electrical steel sheet. The insulating film composition of a non-oriented electrical steel sheet according to the present invention comprises a mixed metal phosphate consisting of aluminum phosphate (Al(H 3 PO 4 ) x=1-3 ) and cobalt phosphate (Co(H 3 PO 4 ) 3 ), and an organic/inorganic composite consisting of epoxy resin and silica (SiO 2 ) nanoparticle substituted on the functional group of the epoxy resin.
